Sun(sm) Alert Notification
* Sun Alert ID: 101776
* Synopsis: Security Vulnerabilities in The "libgdk_pixbuf" Library
May Allow a Remote Unprivileged User the ability to Execute
Arbitrary Code
* Category: Security
* Product: GNOME 2.0 Desktop, Sun Java Desktop System 2003
* BugIDs: 5103573
* Avoidance: Patch, Workaround
* State: Resolved
* Date Released: 23-Jun-2005, 13-Jul-2005
* Date Closed: 13-Jul-2005
* Date Modified: 13-Jul-2005
1. Impact
Due to multiple security vulnerabilities in the libgdk_pixbuf library,
a remote unprivileged user may be able to execute arbitrary code with
the privileges of a local user when that local user has loaded an
XPixmap (Xpm) format image file supplied by an untrusted user.
The libgdk_pixbuf library is part of the GIMP Toolkit (GTK+) and is
used for loading and rendering images.
These issues are described in the following documents:
* http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0782
* http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0783
2. Contributing Factors
These issues can occur in the following releases:
SPARC Platform:
* GNOME 2.0 (for Solaris 8) without patch 114644-03
* GNOME 2.0 (for Solaris 9) without patch 114686-03
* GNOME 2.0.2 (for Solaris 9) without patch 115738-04
x86 Platform
* GNOME 2.0 (for Solaris 8) without patch 114645-03
* GNOME 2.0 (for Solaris 9) without patch 114687-03
* GNOME 2.0.2 (for Solaris 9) without patch 115739-04
* Solaris 9 with JDS release 2 installed
Linux
* Sun Java Desktop System (JDS) 2003 without the updated RPMs
(patch-118903-01)
* Sun Java Desktop System (JDS) Release 2 without the updated RPMs
(patch-118905-01)
Note: Solaris 10 is not affected by these issues.
To determine the version of GNOME that is currently installed on the
system, the following command can be run (output will vary by
platform):
% grep description /usr/share/gnome/gnome-about/gnome-version.xml
<description>fcs-10b</description> for GNOME 2.0 releases
<description>2.0.0_patch-us2</description>
Alternatively (for the same results), in a terminal window from within
the GNOME desktop, the following command can be run:
% /usr/bin/gnome-about
To determine the release of JDS for Linux installed on a system, the
following command can be run:
% cat /etc/sun-release
Sun Java Desktop System - 2003
To determine if JDS release 2 is installed on a Solaris 9 system, the
following command can be run:
% grep distributor-version /usr/share/gnome-about/gnome-version.xml
<distributor-version>Sun Java Desktop System, Release 2</distributor-version>
To determine the version of GTK on JDS for Linux systems, run the
following command:
% rpm -qf /usr/lib/gtk-2.0/2.2.0/loaders/libpixbufloader-xpm.so
gtk2-2.2.2-30
3. Symptoms
There are no reliable symptoms that would indicate the described
issues have been exploited.
4. Relief/Workaround
To work around the described issues, do not load XPixmap (Xpm) images
from untrusted sources.
5. Resolution
These issues are addressed in the following releases:
SPARC Platform
* GNOME 2.0 (for Solaris 8) with patch 114644-03 or later
* GNOME 2.0 (for Solaris 9) with patch 114686-03 or later
